    Sony KDL 40 - tabs bonding?

    Have a Sony KDL-40BX421 - something going on with the screen. Have seen a few threads about tab bonding. Top quarter of the screen looks great - bottom looks like bad panel or T-con. Can't figure where the T-con is on this TV. From the photos any suggestions? And where is the T-con board? Thanks

      One of those integrated T-CON into the panel, not much you can do for fixing the T-CON.
      Looking at the screen shot of the screen, not 100% sure if it is tab bond problem or not.

          Any other options! Any chance of selling any of the parts that are probably still functioning fine? Thanks

              Sony 8K XBR-75Z8H White Screen Vertical Bars Tcon Code. Help Needed🙏
              by Daren87
              Hello everyone,

              I've recently been given a Sony 8k Z8H. It's got a white screen with two vertical black bars. At times it's given me the 5 blink Tcon code. Testing voltage on the Tcon I can see some low or missing voltage. I've done a basic visual check of cables and the COF. Not seeing anything obvious. The original Tcon seemed to have good caps until turning it over. On the bottom I found maybe 10 caps with both sides of the caps shorting to ground. I thought ok these caps and likely other components on the Tcon are shorted so let's try a replacement Tcon. I just received the...

              Macbook 2017 with touchbar (A1706) won't turn on after removing the screen
              by Ryan.man
              Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!

              My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.

              This time the original cable broke too close to the screen, it can't be fixed without tearing the screen...

              Sony KD-55XG9505 lines on screen problem
              by Chrissygizmo
              Hello again everyone,

              This is my latest mission, to try getting this Sony tv back to normal working order…

              I've only just got it today, when you power it up everything is as should be, in fact it works perfectly for a few minutes then the screen starts getting horizontal lines on & eventually the full screen goes back, I will upload photos of the problem & also some photos of the board etc. You might notice that I'm busy trying the tape method, I'm not sure exactly where the clock lines are so I'm just guessing & hoping for the best lol . I've already tried...

              iphone XS turns off when press on screen.
              by smic717394
              Hi,

              I have a iphone XS that came in for a screen replacement, the screen was badly cracked, and inside missing scues, on the back of the screen still the blue protector, the screen was a LCD. So we replaced the screen and all good, installed the screen and we noticed that pressing the screen with a bit of force but not excessive, the phone dies. After plugging the charger it turns back on, but again if you press it it dies. I open the phone again, and I can't see anything major, with the phone open, if I press on the logic board, battery, charging board, or even putting pressure on...

              Sony KD-55AG9 TCON?
              by bbrain
              Hi,

              I have this problem with my Sony 55' AG9.
              It flashes 4x.
              I have found the service manual, and seems it is the TCON.

              Before I buy a TCON can someone check the vid?



              Thanks in advance!...
